Was just wondering whether anyone has had any experience with this unit. Joe Brancato sells them for a set up on tanks other than what he sells. I have an Omega 75 footer that I would love to be able to regulate the air flow a little bit better. My valve on top sticks somethin terrible and always goes full speed ahead or dead stopped … no middle of the road. Tried the restrictor screw in the valve and it actually made things worse. Anyway, has anybody had some experience with this valve and is it worth $229. Supposedly you get a new 300 Din valve, 40" microbore hose and all the fittings attached. Does anybody know how the restrictor works in the Din valve, how is it different than the one I have that came with the Omega which merely has a small hex head screw that is SUPPOSED to slow the flow? If anybody has some information on the TJ3 SLO-FLO 300 DIN Valve, I'd surely appreciate it. Really don't want to end up with basically the same thing I have now.
